That's a lot of extra prerequisites. Is this needed during the build when configured with --enable-criu-support, the normal testing cycles, or only when attempting to use the CRIU functionality? I'm guessing there will be some new tests in the suites (functional?) to cover this?

[smlambert]

re: new tests, CRIU is a major new feature, this is an example and first of many new tests to be added eclipse-openj9/openj9#14531.

@vsebe Can you confirm the answers to these questions from earlier please:

Is this needed during the build when configured with --enable-criu-support, the normal testing cycles, or only when attempting to use the CRIU functionality?

Also a couple of extra points:

1. Ubuntu 16 is out of support - is that still required? There have been two new LTS releases since 18 and they are not covered here. We have a wide set of test platforms that won't have anything installed by the role - is that ok?
2. This role is not being called by the top level main.yml in this PR. Is that intentional (i.e. are you calling it elsewhere in your setup of the OpenJ9 project's machines?

Yes to all. It is required for building and testing OpenJ9 with criu support for JDK11+. Criu support for build is enabled with --enable-criu-support configure option. There are new sanity.functional tests enabled for our nightly pipelines. So far we enabled it only for linux x86, other linux platforms to be enabled later (see eclipse-openj9/openj9#14531 for further details).

We still have Ubuntu16 machines on openj9-jenkins. This PR addresses 16, 18 and 20.
I will add 22 shortly.
The role should not run on your machines since it is not added to the AdoptOpenJDK_Unix_Playbook/main.yml.

2. This role is not being called by the top level main.yml in this PR. Is that intentional (i.e. are you calling it elsewhere in your setup of the OpenJ9 project's machines?

Yes, it is. We have a different top level playbook for the IBM machines.

@sxa fyi

[vsebe]

I updated the task for Ubuntu 22.

[sxa]

Yes, it is. We have a different top level playbook for the IBM machines.

On that basis I'm ok with it. Thanks for all the clarifications on the above points too - good to know :-) As long as we continue to build without --enable-criu-support it shouldn't affect us then.
